No matter the weather, nothing can stop you from making gains in the NB HEATLOFT Pant for men. This modernized, winter-proofed take on a traditional sweatpant is cut from stretchy ponte knit fabric with a NB HEATLOFT insertion knit panel alongside the thigh and back of the calf to deliver superior heat retention while wicking sweat away. Meanwhile, the clean-cut modern aesthetic gives you style points when you take it to the streets.
